HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 418, 835, 686 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 418, 835, 686 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 418, 835, 686 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 418, 835, 686 is 1.
HCF(418, 835, 686) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 418, 835, 686 is 1.
Step 1: Since 835 > 418, we apply the division lemma to 835 and 418, to get
835 = 418 x 1 + 417
Step 2: Since the reminder 418 ≠ 0, we apply division lemma to 417 and 418, to get
418 = 417 x 1 + 1
Step 3: We consider the new divisor 417 and the new remainder 1, and apply the division lemma to get
417 = 1 x 417 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 418 and 835 is 1
Notice that 1 = HCF(417,1) = HCF(418,417) = HCF(835,418) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 686 > 1, we apply the division lemma to 686 and 1, to get
686 = 1 x 686 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 686 is 1
Notice that 1 = HCF(686,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
